Pokémon Ash Gray Walkthrough: Complete Guide to Beating Every Gym and Rival in 2026

Pokémon Ash Gray has earned its place as one of the most polished fan-made Pokémon games out there. If you’re jumping into this ROM hack for the first time, or you’re stuck on a particular gym leader, this walkthrough covers everything you need to know. We’ll break down every major battle, optimal team compositions, grinding spots, and the strategies that’ll get you through to Champion status. Whether you’re playing on an emulator or considering it, this guide has you covered with exact stats, trainer lineups, and the meta-game knowledge veteran players rely on.

What Is Pokémon Ash Gray?

Pokémon Ash Gray is a ROM hack of Pokémon FireRed that reimagines the canonical story of the anime series. Rather than playing as a generic trainer, you’re essentially following Ash Ketchum’s journey through the Kanto region, battling the same gym leaders, catching many of the same Pokémon, and facing off against Gary Oak as your primary rival. The hack stays remarkably faithful to the show’s plot beats while integrating gameplay mechanics that make it feel like a legitimate Pokémon experience.

One of the game’s biggest draws is its anime-accurate team compositions and trainer setups. Gym leaders here aren’t pushovers with three Pokémon, they’ve got full six-member teams that actually pose a threat. That means preparation matters. The game launched originally as a Ruby/Sapphire ROM hack but evolved into a FireRed-based version, which is the most widely played iteration today.

If you’re familiar with other ROM hacks like Pokémon Blazed Glazed or Pokémon Dark Rising, Ash Gray occupies a sweet spot: it’s challenging without being impossibly hard, story-driven without losing mechanical depth, and respectful of the source material without feeling gimmicky. For players who loved the anime and want a game that captures that spirit, this is the gold standard.

Game Basics and Getting Started

Before you venture into Viridian Forest, getting the fundamentals down makes a massive difference. Pokémon Ash Gray follows the standard FireRed progression but with tweaked wild Pokémon availability and trainer difficulty curves. You’ll start in Pallet Town, get your Pokédex from Professor Oak, and immediately face your first rival battle.

Choosing Your Starter Pokémon

Your starter choice in Ash Gray matters more than in vanilla FireRed because the game’s structure encourages keeping your team balanced. The three options are Bulbasaur, Charmander, and Squirtle, the same trio as the show.

Bulbasaur is arguably the strongest starter for early-game dominance. Grass typing gives it advantages against Brock and Misty, and Leech Seed becomes a powerful utility move by mid-game. Its bulk lets you tank hits in trainer battles when you’re building your team.

Charmander starts weakest statistically but becomes a powerhouse by late-game when it evolves into Charizard. You’ll struggle against Brock and have a rough time in gym battles until Charmeleon, but the late-game payoff is real. If you’re comfortable grinding, Charmander rewards player skill.

Squirtle rounds out the trio with solid defensive stats and useful typing against Fire and Rock gym leaders. It’s the most “safe” pick, no glaring weaknesses, no glaring strengths. It’ll get you through the game comfortably without requiring careful team composition.

The meta recommendation? Start with Bulbasaur on your first playthrough. The early advantages keep you ahead of the curve, and you’ll understand the game’s difficulty better.

Early Game Tips and Strategies

The first two gym battles, Brock and Misty, set the tone for how seriously you need to treat type matchups. Brock’s Onix can be outspeeded by nearly everything and has terrible special defense. Misty’s team hits harder: her Staryu has solid speed and special attack.

Your first priority should be catching a Mankey in Route 22 (west of Viridian City). Mankey learns Low Kick at level 6, which absolutely shreds Brock’s team. This single catch-and-train decision can make Brock a trivial fight. Alternatively, if you started Bulbasaur, just spam Vine Whip, it’s neutral against Rock and you’ll outspeed everything Brock throws at you.

For Misty, you want Electric or Grass types. A Pikachu from Route 3 or Route 2 works well: Electric attacks hit her Water types hard. If you went Bulbasaur, your starter handles Misty reasonably well, though her Lapras can be problematic because of its stats and move pool.

Don’t overlook the “junk” Pokémon early. That Pidgeot from Route 1-3 becomes a fantastic team member, it has good speed, learns Brave Bird eventually, and provides crucial coverage. Nidoran-M or Nidoran-F caught in Route 3 evolve into bulky physical attackers that carry your team through early-to-mid game.

Level distribution matters. Aim to have your team at or slightly above the level of gym leader teams. Underleveled teams die fast, no matter the type advantage. Grinding in early routes takes time but saves you from frustrating wipe-outs later.

Gym Leader Battles: Complete Walkthrough

This is where the real challenges begin. Pokémon Ash Gray’s gym leaders aren’t joke trainers, they have full rosters, held items, and move pools designed to pressure you. Here’s the detailed breakdown for each encounter.

Brock’s Rock-Type Gym

Location: Pewter City
Pokémon Team:

• Onix (Lv. 12), Rock Head ability, knows Tackle, Harden, Bind, Headbutt
• Rhyhorn (Lv. 12), Lightning Rod ability, knows Fury Attack, Tail Whip, Stomp
• Geodude (Lv. 10), Rock Head ability, knows Tackle, Defense Curl, Magnitude

Brock is designed to be beatable with type advantage but punishing if you ignore it. His Onix has terrible special defense, so special moves demolish it. Bulbasaur’s Vine Whip one-shots it. A Mankey with Low Kick does the same. Even Pikachu with Thunderbolt takes it out in two hits.

The trap is Rhyhorn, it has more bulk and raw attacking power. Physical moves bounce off its decent defense, but it’s slow and has no way to handle special attackers. If you have a Staryu or Magikarp (water Pokémon have good special attack), switch to it when Rhyhorn comes in.

Geodude is the weakest of the three and rarely becomes a threat. Priority is dealing with Onix first, then Rhyhorn. Use type advantage ruthlessly. Don’t try to “tank and grind” Brock, that’s not how this game works.

Recommended Team: Bulbasaur/Mankey/Pikachu, + one Pokémon with a water move, + two flexible slots. You don’t need a full six-member team yet.

Misty’s Water-Type Gym

Location: Cerulean City
Pokémon Team:

• Staryu (Lv. 16), Natural Cure ability, knows Tackle, Harden, Water Gun, Rapid Spin
• Goldeen (Lv. 16), Water Veil ability, knows Peck, Tail Whip, Water Sport, Fury Attack
• Lapras (Lv. 18), Water Absorb ability, knows Sing, Mist, Water Gun, Body Slam

Misty’s team jumps in level and stat distribution. Staryu is fast and can hit hard with special attacks, it’s the primary threat. Lapras is the real MVP of her team: high HP, decent bulk, Sing status move for control, Body Slam for flinch chance. Goldeen is the weakest and primarily serves as a mid-battle switch.

Your goal is getting Electric or Grass types in play. A trained Pikachu with Thunderbolt handles Staryu cleanly. Bulbasaur with Vine Whip and Leech Seed can stall Misty’s team over several turns, healing as you damage them. Nidoqueen (if you trained Nidoran-F) resists Water and hits back hard with Ground moves.

Lapras is the problem child. It hits harder than the other two, has good bulk, and Sing can put you to sleep mid-battle. If you don’t have Electric attacks, it wears you down. Bring antidotes or Full Heals. If you’re running Bulbasaur, switch in when Lapras appears and spam Leech Seed, it’s one of the few moves that doesn’t get resisted.

Recommended Team: Electric or Grass type as your main carry, + Psychic type (for Goldeen), + bulky Pokémon to soak Lapras attacks, + two support Pokémon. You’re looking at a 5-6 member team here.

Lt. Surge’s Electric-Type Gym

Location: Vermilion City
Pokémon Team:

• Voltorb (Lv. 20), Static ability, knows Magnetic Flux, Sonic Boom, Thunder Wave, Self-Destruct
• Pikachu (Lv. 20), Static ability, knows Thunder Wave, Agility, Quick Attack, Thunderbolt
• Magneton (Lv. 21), Magnet Pull ability, knows Supersonic, Thunder Wave, Spark, Metal Sound
• Raichu (Lv. 24), Static ability, knows Quick Attack, Thunder Wave, Thunderbolt, Iron Tail

Lt. Surge fields an all-Electric team, which sounds like a weakness, but Electric Pokémon have surprisingly limited offensive coverage outside of Electric attacks. His team heavily relies on paralysis (Thunder Wave) and speed.

Voltorb leads and can Self-Destruct if cornered, which is annoying but survivable. Switch in a Ground-type and it becomes a non-issue, Ground types are immune to Electric attacks entirely. Magneton is the biggest threat because of Magnet Pull, which can trap Steel types (not that you have many yet).

Raichu is Surge’s ace and has the highest offensive stats. Thunderbolt hits hard, and Iron Tail provides surprise coverage. The good news? All of his Pokémon are slow compared to something like Pidgeot or a trained Mankey.

Your Ground-type counter-team is paramount. A Diglett or Dugtrio caught in Diglett’s Cave (accessible after beating Misty) solos most of Surge’s team. Its immunity means Thunder Wave doesn’t matter, and Earthquake hits everything except Voltorb (which Self-Destructs). If you don’t have Ground access yet, Water types like Lapras tank Electric moves well.

Recommended Team: Ground-type (Dugtrio preferred), Water-type for defense, Grass-type for coverage, + bulky Pokémon, + speedy Pokémon for priority, + one flexible slot.

Erika’s Grass-Type Gym

Location: Celadon City
Pokémon Team:

• Exeggcute (Lv. 26), Chlorophyll ability, knows Synthesis, Leech Seed, Reflect, Egg Bomb
• Vileplume (Lv. 27), Chlorophyll ability, knows Acid Powder, Leech Seed, Synthesis, Solar Beam
• Tangela (Lv. 26), Chlorophyll ability, knows Vine Whip, Sleep Powder, Leech Seed, Growth
• Victreebel (Lv. 28), Chlorophyll ability, knows Acid Powder, Leech Seed, Sleep Powder, Solar Beam

Erika’s gym is a turning point in difficulty. All four Pokémon are bulky, can heal with Synthesis, and use Sleep Powder to disable your team. This is the first fight where you can’t just brute-force type advantage.

Vileplume and Victreebel are the threats, both have solid stats and strong moves. Vileplume’s Acid Powder hits special defense, while Victreebel can hit physically. Tangela is surprisingly bulky and Sleep Powder is the move to respect most here. Exeggcute, even though being lower level, has high defense and Reflect support for the team.

Fire and Flying types are your friends here. A Charizard (if you started Charmander) handles this gym solo. Pidgeot with Brave Bird (learned later, but it’s available) or even Wing Attack chunks through the Grass types. Ice types work too, Lapras handles this gym well with Ice Beam.

The key is preventing Sleep Powder from controlling the fight. Switch rapidly when Sleep Powder comes out. Bring Full Heals and Full Restores into this battle. If you get caught in the sleep/Leech Seed loop, you lose.

Recommended Team: Fire-type or Flying-type as your primary carry, Ice-type for backup, Water-type for Reflect defense, + two support Pokémon that aren’t weak to Grass. Bring healing items.

Koga’s Poison-Type Gym

Location: Fuchsia City
Pokémon Team:

• Koffing (Lv. 30), Levitate ability, knows Poison Gas, Sludge Bomb, Toxic Spikes, Mist
• Muk (Lv. 30), Sticky Hold ability, knows Sludge Wave, Poison Powder, Acid Armor, Gunk Shot
• Weezing (Lv. 31), Levitate ability, knows Poison Gas, Sludge Bomb, Smokescreen, Explosion
• Venomoth (Lv. 32), Shield Dust ability, knows Toxic Spikes, Poison Powder, Psychic, Sludge Bomb

Koga’s team is bulky, defensive, and uses status moves effectively. The big problem here is Muk, raw special attack and physical bulk make it a problem. Venomoth with Psychic can hurt you back, and Weezing has Explosion for a last-ditch nuke.

Poison attacks don’t have great coverage in the meta, most Pokémon just tank them. The real threat is the status moves (Poison Powder, Toxic Spikes) and raw bulk. Ground-type moves (Earthquake, Magnitude) hit most of Koga’s team hard. Psychic moves hit Muk neutral but handle Venomoth super-effectively.

A trained Dragonite (if you have one) walls most of this team. Psychic types like Alakazam or Jynx can beat Venomoth and Muk with the right move set. If you’re struggling, Dugtrio with Earthquake handles the Poisons that don’t have Levitate.

Recommended Team: Psychic-type or Ground-type as your carry, Grass-type for Muk, Flying-type for speed, + bulky Pokémon to tank Sludge attacks, + two support Pokémon.

Sabrina’s Psychic-Type Gym

Location: Saffron City
Pokémon Team:

• Espeon (Lv. 33), Magic Bounce ability, knows Psybeam, Psychic, Swift, Power Swap
• Alakazam (Lv. 34), Magic Guard ability, knows Psybeam, Psychic, Shadow Ball, Focus Blast
• Mr. Mime (Lv. 33), Filter ability, knows Psybeam, Psychic, Light Screen, Barrier
• Alakazam (Lv. 35), Magic Guard ability, knows Psybeam, Psychic, Shadow Ball, Focus Blast

Sabrina’s gym is arguably the toughest leading up to the endgame. Alakazam at Lv. 35 is absurdly fast and hits hard with Psychic. You will be outsped by nearly everything she throws if your team is only level 35-36. Magic Guard is a pain, it blocks damage from abilities like Toxic Spikes or hazards.

Dark types are immune to Psychic attacks and necessary for this gym. A trained Houndoom or Umbreon (if you have one) tanks her entire team. Tyranitar is overkill defensively but excellent. Ghost types also hit Psychic types super-effectively.

Alakazam is her ace and will threaten a full team if you’re not careful. Its special attack is absurdly high, and Focus Blast (if it hits) does massive damage to non-resisting Pokémon. The strategy is outspeeding her with Dark-types or switching into something that walls Psychic entirely.

Recommended Team: Dark-type (Houndoom/Umbreon/Tyranitar), Ghost-type, Bug-type, + bulky Pokémon, + two support Pokémon. This gym requires type coverage over raw stats.

Blaine’s Fire-Type Gym

Location: Cinnabar Island
Pokémon Team:

• Arcanine (Lv. 36), Flash Fire ability, knows Extreme Speed, Flare Blitz, Wild Charge, Close Combat
• Rapidash (Lv. 36), Flash Fire ability, knows Fury Attack, Fury Attacks, Bounce, Fury Attack
• Ninetales (Lv. 37), Drought ability, knows Fire Spin, Flare Blitz, Nasty Plot, Solar Beam
• Charizard (Lv. 38), Blaze ability, knows Extreme Speed, Flare Blitz, Dragon Dance, Dragon Claw

Blaine’s team is fast and hits hard. This gym requires Water, Ground, or Rock coverage primarily. Arcanine and Charizard are the threats, both have high attack stats and priority moves. Ninetales is actually defensive with Drought and Solar Beam stalling potential. Rapidash is the weakest link.

Water-type Pokémon are your best bet. Lapras, Blastoise, or Gyarados handle most of his team well. Ground-types resist Fire and can hit back hard with Earthquake. Rock-types resist Fire and handle Charizard well.

The tricky part is Charizard’s Dragon Dance, which boosts its attack and speed, making it a sweeper. Kill it before it gets more than one or two boosts. If you have a Water type, switch in immediately and spam Water attacks.

Recommended Team: Water-type (Lapras or Blastoise), Ground-type (Dugtrio works fine), Rock-type if available, + bulky Pokémon, + speed-based Pokémon, + one support slot.

Giovanni’s Dark-Type Gym

Location: Viridian City (Post-Game, technically)
Pokémon Team:

• Rhydon (Lv. 45), Lightning Rod ability, knows Earthquake, Stone Edge, Megahorn, Swords Dance
• Dugtrio (Lv. 45), Arena Trap ability, knows Earthquake, Stone Edge, X-Scissor, Swords Dance
• Nidoking (Lv. 46), Sheer Force ability, knows Earthquake, Sludge Bomb, Iron Head, Swords Dance
• Weezing (Lv. 45), Levitate ability, knows Sludge Wave, Explosion, Toxic Spikes, Dark Pulse
• Tyranitar (Lv. 47), Sand Stream ability, knows Earthquake, Stone Edge, Crunch, Swords Dance
• Nidoking (Lv. 48), Sheer Force ability, knows Earthquake, Sludge Bomb, Iron Head, Crunch

Giovanni is the final gym leader and significantly tougher than Blaine. His team is built around Earthquake spam, five of his six Pokémon learn it. The Swords Dance setup is dangerous on his physical attackers.

Water and Ice attacks are crucial here. Giovanni heavily leverages Ground-type offense, so Flying-type Pokémon (which are immune to Earthquake) are your friends. Dragonite or Salamence handle most of his team. Water-types resist Ground and can hit back hard.

Tyranitar is his ace and will sweep if given the chance. Its special defense is lower, so special attacks (particularly Water-type) handle it well. Kill it quickly or switch into something that tanks Earthquake entirely.

Recommended Team: Flying-type (Dragonite/Salamence), Water-type, Ice-type, + bulky Pokémon, + Psychic-type, + one flexible slot.

This fight is where your prep work matters most. If you’ve been grinding and building a coherent team with type coverage, you’ll win. If you’re running six random Pokémon, expect a wipe.

Rival Battles and Key Encounters

Gary Oak is your real antagonist in Pokémon Ash Gray, and the game makes sure you fight him repeatedly. Understanding his team composition and strategy across multiple battles is crucial.

Gary Oak Confrontations

You’ll face Gary four times throughout the game: once in Pallet Town (starter battle), once in Viridian Forest, once before Mt. Moon, and once in Cinnabar Island (post-Blaine). Each time his team gets stronger and more competent.

Pallet Town (Lv. 5): This is a tutorial battle. Gary has whatever starter is strong against yours. If you started Squirtle, he runs Bulbasaur. His team is minimal, and the battle is unloseable. Don’t stress.

Viridian Forest (Lv. 10-12): Gary now has a small team: his starter (Lv. 11) and Pidgeot (Lv. 10). His starter will have its strongest move available at that level. This is your first real rival battle, and it tests your type knowledge. Use something that counters his starter, Water beats Fire, Fire beats Grass, Grass beats Water. His Pidgeot is fragile but fast. Priority moves or strong special attacks finish it in one hit.

Mt. Moon (Lv. 17-19): Gary has his fully evolved starter at Lv. 18 and Gyarados (Lv. 18), plus Alakazam (Lv. 17). This fight is significantly harder. Alakazam’s speed outspeeds most teams, and Gyarados’s raw bulk is problematic. His starter hits hard now. You need a cohesive team with type coverage. Bring Antidotes for Poison moves his starting Pokémon might learn.

Cinnabar Island (Lv. 42-44): This is the final rival battle and the hardest of his encounters. Gary’s team at this point is:

• Charizard (Lv. 43), Fire Flying, knows Flare Blitz, Dragon Claw, Earthquake, Roost
• Gyarados (Lv. 43), Water Flying, knows Waterfall, Earthquake, Stone Edge, Crunch
• Alakazam (Lv. 44), Psychic, knows Psychic, Focus Blast, Shadow Ball, Trick
• Arcanine (Lv. 43), Fire, knows Flare Blitz, Close Combat, Earthquake, Extreme Speed
• Exeggutor (Lv. 43), Grass Psychic, knows Psychic, Solar Beam, Focus Blast, Earthquake
• Blastoise (Lv. 45), Water, knows Waterfall, Earthquake, Stone Edge, Focus Blast

This team is balanced, hits hard, and covers a lot of bases. Alakazam will outspeed almost everything you throw at it. Blastoise is his ace and has the highest stats. Water coverage is across his team, making Grass-types a liability.

Your strategy should be built around outspeeding or tanking Alakazam, dealing with Blastoise quickly with Electric or Grass attacks, and preventing Charizard from setting up. A Dragonite or strong Electric type handles Charizard and Gyarados well. Bring a physical wall for his physical attackers, something like Tyranitar or Zapdos tanks hits and hits back hard.

Other Important Trainer Battles

Gary isn’t the only rival you’ll face. There are critical trainer encounters throughout the game:

Brock’s Boulder Badge fight involves battling him in-gym, but his team outside the gym is different. If you encounter him elsewhere (unlikely in Ash Gray’s structure), his team shifts.

Misty appears in the Cerulean Gym and occasionally elsewhere with a trained team.

Giovanni’s battles escalate. You fight him in Celadon City (Team Rocket takeover) before the final Gym Leader battle. His team in the Rocket takeover is weaker than his Gym Leader team, it’s a “story beat” battle rather than a climactic fight.

The game includes trainer rematches in specific locations if you return after beating them. Check Viridian Forest and Route 1 for repeated encounters that can help you grind experience while testing team builds.

Key takeaway for rival battles: Gary’s team showcases what a “balanced” competitive team looks like. Build your team with similar principles, type coverage, speed control, bulk for tanking, and offensive pressure. You’re trying to mirror his strategy while exploiting his weaknesses.

Leveling Up Your Team and Pokédex Completion

Grinding isn’t fun, but underleveled teams get demolished in Pokémon Ash Gray. You need a strategy for efficient leveling and team building.

Best Grinding Locations

Routes 3 and 4 (Levels 8-16): Early-game grinding here for your first team. Rattata, Mankey, Pidgeot, Nidoran, and Jigglypuff all appear. Battles are quick, and experience gain is reasonable. Use Pokémon with experience-boosting abilities like Exp Share. This is also where you’ll catch Sandshrew and Vulpix if you want Fire or Ground coverage early.

Diglett’s Cave (Levels 18-22): Once you have access (after beating Misty), this cave is fantastic. Diglett and Dugtrio give good experience, and you can catch Dugtrio here to add to your team. Grinding here prepares you for Lt. Surge.

Rock Tunnel (Levels 16-22): High experience rewards, but it’s optional story-wise in Ash Gray. If you need a level bump before Cerulean, skip this and just grind Routes 1-2. If you’re grinding post-Erika, Rock Tunnel speeds up leveling significantly.

Route 8 and Route 9 (Levels 30-35): These are your mid-game grinding spots. Rhyhorn, Growlithe, Doduo, and other solid Pokémon appear. Trainers here also have decent teams if you want EV-rich battles.

Routes 16-18 and Route 23 (Levels 35-45): For pre-Elite Four grinding, these routes have high-level Pokémon. Route 23 specifically has high-level encounters that reward experience heavily. If you’re within 10 levels of the Elite Four, one session here gets you competitive.

Experience Share Mechanics: In Ash Gray (based on FireRed mechanics), Experience Share is a held item that distributes 50% of battle experience to the holder even if they don’t fight. If you have one, use it on your weakest team member to level them up while your strong Pokémon train.

Optimal grinding strategy: Never grind alone. Always have your entire team in battle rotation. Switch Pokémon constantly so experience spreads. Don’t let one Pokémon dominate, balanced teams are stronger than one-man armies.

Catching Essential Pokémon

Your team doesn’t need to include Pokémon from Kanto’s native dex to be effective, but certain catches are essential for type coverage.

Dugtrio (Route 2, Route 11 pre-evolution form Diglett): Ground-type with high speed. Earthquake is mandatory coverage against Electric, Poison, and Fire. Catch this early and train it. It’s incredibly valuable.

Dragonite (You need to catch Dratini in Route 10). Dragon-type with excellent stats and movepool. Takes more grinding to get Dragonite, but it’s one of the best team members in the game. Lv. 30 evolution is steep, but the payoff is real.

Lapras (Found in Silph Co.). Water Ice-type with excellent defensive bulk and special attack. One of the best generalist Pokémon. If you missed catching one from Misty’s team interaction, Silph Co. has them.

Dragonair (Lv. 30 evolution of Dratini from Route 10). If you don’t want to grind to Dragonite, Dragonair at Lv. 35 is usable for the mid-game.

Graveler/Golem (Catch Geodude in Rock Tunnel, evolve via trade). High defense, Earthquake user, essential for certain gym leaders. If you can’t trade, use Rhydon from Route 23 instead.

Gengar (Catch Haunter in Pokémon Tower or Lavender Town). Ghost-type with excellent speed and special attack. Shadow Ball is surprisingly useful for coverage. If you can’t trade to evolve it, Haunter still hits hard.

Alakazam (Catch Abra anywhere with Synchronize ability or just spam Pokéballs). Psychic-type with absurdly high special attack and speed. One of the best special attackers in Ash Gray.

Charizard (If you didn’t start with Charmander, catch Charmander in Route 3 or buy it from the Pokémart in Route 24). Fire-type with good offensive stats and movepool. Covers Grass and Bug weaknesses.

Blastoise (If you didn’t start with Squirtle, catch one in Cinnabar Island post-game or get it from breeding). Water-type with high special attack and good coverage moves.

Pidgeot (Catch Pidgeot in Routes 1-3). Flying-type with decent speed and attack. Brave Bird is a fantastic move. One of the most underrated team members.

Optimal team composition: You want one Pokémon for each type weakness you encounter, not one for each type. A balanced team has roughly:

• One fast special attacker (Alakazam)
• One bulky physical attacker (Arcanine or Tyranitar)
• One defensive wall (Lapras or Umbreon)
• One coverage Pokémon (Dugtrio for Ground, Gyarados for physical Water)
• One glass cannon (fast hard hitter)
• One flexible pick

Diversify types, but optimize for coverage. Don’t run two Water-types unless there’s a specific strategy, you’re wasting team slots.

Elite Four and Champion Battle Guide

The Elite Four are where your preparation pays off or fails catastrophically. This is the endgame, and these trainers have full teams with held items, abilities, and move sets designed to exploit weaknesses.

Preparing for the Final Challenges

Before you enter the Elite Four, your team should be level 45-50 minimum. Lower than that and you’re relying on items to carry you. Stock up on Full Heals, Full Restores, Antidotes, Full Paralyzes Heals, Awakenings, and Revives. You can’t out-item difficult battles, but having proper healing support prevents stupid losses to poison or paralysis.

Your six team members should have diverse types and strong move pools. Each should have at least one move that hits hard and one that provides coverage. For instance, Dragonite needs Dragon Dance for sweeping, Dragon Claw for STAB, Outrage for coverage, and Earthquake for utility.

Move sets matter more here than stats. A Lv. 45 Pokémon with the right four moves beats a Lv. 50 Pokémon with a bad move pool. Review what each Elite Four member uses and plan your switches accordingly.

Prepare for held items. The Elite Four uses items like Choice Specs, Life Orb, Assault Vest, and Leftovers. Pokémon with held items heal, boost stats, or provide passive benefits. This is the first time you need to understand item economy.

Defeating Each Elite Four Member

Elite Four Member 1: Lorelei (Ice-type specialist)

Lorelei’s team:

• Lapras (Lv. 50)
• Slowbro (Lv. 50)
• Cloyster (Lv. 50)
• Piloswine (Lv. 50)
• Dewgong (Lv. 51)

All Ice-types with high bulk and special attack. Steel and Fire types are ideal here, Arcanine handles most of her team, Dugtrio is immune to Piloswine’s Ice Shard priority, and Lapras (if you have one) tanks hits well.

LoeWLei’s weakness: She doesn’t have many moves that hit Fire or Steel hard. Arcanine with Flare Blitz can sweep a significant portion of her team if it gets going. Lapras can also wall her attacks and hit back with Electric coverage.

Strategy: Lead with something that resists Ice and forces switches. Build up offensive boosts if possible. Avoid letting her set up Calm Mind or special attack boosts, that destroys your bulk.

Elite Four Member 2: Bruno (Fighting-type specialist)

Bruno’s team:

• Onix (Lv. 50)
• Hitmonchan (Lv. 50)
• Hitmonlee (Lv. 50)
• Machop (Lv. 50)
• Machoke (Lv. 51)

Fighting-types with high attack and speed. Flying, Psychic, and Fairy coverage are essential. Alakazam can outspeed most of his team and hit hard with Psychic. Pidgeot with Flying attacks handles Fighting-types well.

Bruno’s weakness: His team is slow and lacks special attack. Psychic moves hit his team super-effectively. Alakazam can sweep a significant portion of his team if it doesn’t take a critical hit first.

Strategy: Lead with a Psychic or Flying type. Switch to something bulky if he brings out Machoke (which has the highest stats). Don’t let Hitmonlee get Swords Dance off, it becomes a problem.

Elite Four Member 3: Agatha (Poison-type specialist)

Agatha’s team:

• Arbok (Lv. 50)
• Weezing (Lv. 50)
• Muk (Lv. 50)
• Vileplume (Lv. 50)
• Gengar (Lv. 51)

Poison-types with status moves and decent bulk. Psychic and Ground coverage handle most of her team. Dugtrio with Earthquake hits most of her team hard. Alakazam can outspeed Gengar and hit it with Psychic or Shadow Ball.

Agatha’s weakness: Status moves are her primary strategy, not raw damage. Bring status cures. Her Pokémon lack strong special attack outside Gengar.

Strategy: Lead with Psychic or Ground. Don’t switch into status moves unnecessarily. Gengar is faster than most Pokémon, so if it uses Shadow Ball, it hits hard. Plan for it to move first in switches.

Elite Four Member 4: Lance (Dragon-type specialist)

Lance’s team:

• Dragonite (Lv. 52), Ace Pokémon
• Dragonite (Lv. 50)
• Aerodactyl (Lv. 50)
• Blastoise (Lv. 50)
• Lapras (Lv. 51)

Lance uses Dragon and Water types, with Dragonite as his ace. Dragon-type moves hit most teams hard. Ice coverage is essential, Lapras can tank Dragon moves and hit back with Ice Beam. Electric types handle Blastoise and Lapras.

Lance’s weakness: His team is slower than expected and lacks Fire coverage. Arcanine or Charizard can hit his team hard with Fire-type moves. Ice-type moves shut down Dragonite hard.

Strategy: Lead with Ice or Electric coverage. Don’t switch into Dragon moves without a resistant or bulky Pokémon. His Dragonite will use Dragon Dance, so disable it quickly or switch into something that tanks its boosted attacks. This is the hardest Elite Four member because Dragonite is an incredible sweeper.

Champion Battle Strategy

Champion: Gary Oak (Final Battle)

Gary’s team for this battle:

• Charizard (Lv. 54), Ace Pokémon
• Blastoise (Lv. 54), Second Ace
• Venusaur (Lv. 54)
• Alakazam (Lv. 53)
• Arcanine (Lv. 53)
• Dragonite (Lv. 55), True Ace

Gary’s team is balanced, hits hard, and covers a massive amount of bases. Dragonite is his true ace and will sweep your team if it gets Dragon Dance off. Alakazam outspeeds almost everything.

This battle is decided by switching and prediction. You can’t brute force through Gary, you have to outplay him. Charizard hits with Fire-type moves, Blastoise with Water, Venusaur with Grass/Poison. Arcanine is physical threat, Alakazam is special threat, Dragonite is mixed sweeper.

Optimal strategy:

1. Lead with something that forces a switch or gets off a utility move. Dugtrio with Earthquake is a solid lead, it threatens Arcanine and forces a switch.
2. Play around Alakazam. It will outspeed your Pokémon. If you can’t outspeed it, switch to something it doesn’t hit hard and use that opportunity to predict his next switch.
3. Dragonite is the real threat. If you have an Ice-type Pokémon like Lapras, keep it alive for Dragonite. One Ice Beam kills it or forces a switch.
4. Blastoise and Charizard are strong but have exploitable weaknesses. Electric moves hit Blastoise, Ground moves hit Charizard. If you have Dugtrio, it sweeps both.
5. Venusaur is the slowest of his team. Hit it hard with Fire or Ice and it goes down quickly.
6. Manage your team’s HP carefully. Don’t waste Pokémon on his weaker team members, you need them alive for Dragonite.

This is the climax. If you’ve been building your team correctly, grinding appropriately, and learning type matchups from gym leaders, you win. If you’ve been one-tricking Pokémon or ignoring coverage moves, you lose. Gary’s team rewards preparation and punishes complacency.

After the battle, you become Champion. Congratulations, you’ve beaten Pokémon Ash Gray’s main campaign.

Once you’ve beaten the main game, there’s more content and advanced strategies to explore. Pokémon Ash Gray has depth beyond the story campaign.

Secret Items and Rare Encounters

Pokémon Ash Gray hides items and encounters that casual players miss. The game follows FireRed’s item locations mostly, but some adjustments exist.

Hidden TMs and Items:

• TM Thunder Wave is hidden in the Vermilion City power plant, useful for paralyzing bulky Pokémon.
• TM Earthquake is in Victory Road, one of the best moves in the game. Every team should have access to it.
• Life Orb is hidden in Silph Co., powerful held item that boosts damage but drains HP. Risky but effective on sweepers.
• Weakness Policy is scattered in various locations, boosts stats when hit super-effectively. Useful for defensive pivots.
• Choice Specs can be found in late-game areas, locks you into one move but massively boosts special attack.

Rare Pokémon Encounters:

• Mewtwo appears in Cerulean Cave post-game. It’s incredibly strong (Lv. 70) and requires a Master Ball or significant preparation to catch. Ultra Balls with multiple attempts work, but it’s slow.
• Articuno, Zapdos, Moltres (Legendary Birds) roam Kanto post-game. These are post-game encounters that appear randomly in specific routes. Catching them requires patience and a Pokémon with Mean Look or Block to prevent them from fleeing.
• Nidoking/Nidoqueen can be bred from Nidoran in the game, providing excellent coverage Pokémon if you missed catching them earlier.

Secret Evolutions:

• Pokémon with trade evolutions like Alakazam or Machamp can be evolved in-game without trading if you find specific NPCs or items. This varies by ROM hack version, so check locally for exact methods.

Post-Game Content

Cerulean Cave and Mewtwo:

After beating the Champion, Cerulean Cave opens. Mewtwo waits at the end. It’s a legendary encounter at Lv. 70, significantly higher than your team likely is. Bring Pokémon that can hit it hard or tank its moves. Alakazam can outspeed it, Lapras can soak hits, Dragonite can tank and hit back.

The catch rate on Mewtwo is abysmal without a Master Ball. Bring 50+ Pokéballs, Ultra Balls, or Timer Balls (which increase catch rate after turns in battle). Use a Pokémon with a non-damaging move to whittle it down, Thunder Wave for paralysis, Sing for sleep. Don’t one-shot it, lower its HP slowly and use status moves to make catching easier.

Trainer Rematches:

Various trainers in the game will rematch you post-game with stronger teams. These are optional but valuable for grinding experience and testing new team compositions. Gym leaders and Elite Four members can be rematched once you return to their locations after beating the Champion.

Pokédex Completion:

After beating the game, you can pursue Pokédex completion. Kanto has 151 Pokémon, but not all are available in a single playthrough. You’ll need to trade or soft-reset to catch different versions (Red/Blue exclusives). If you’re playing solo on an emulator, you might be locked into one version’s availability unless the ROM hack modifies encounter rates.

Moveset Optimization:

Post-game, you can visit Move Tutors who teach stronger moves to your Pokémon. These are located in specific cities and offer moves like Earthquake, Outrage, Psychic, Waterfall, and Stone Edge, the meta staples. If you didn’t teach these moves during the story, post-game is when you optimize movesets.

Nature and IV Farming:

While Pokémon Ash Gray doesn’t modify IV mechanics significantly, understanding natures (which affect stats) helps you understand why certain Pokémon perform differently. A Dragonite with a Jolly nature (boosts Speed, reduces Sp. Attack) outspeeds threats that a Modest Dragonite (boosts Sp. Attack, reduces Speed) doesn’t. Post-game breeding lets you optimize this if you care about competitive viability.

Competitive Team Building:

If you want to experiment with competitive teams, post-game is the time. Build teams designed to counter specific threats, test movesets variations, and understand the meta-game deeply. Teams that steamroll the AI might struggle against optimized competitive Pokémon, the challenge shifts from story progression to tactical depth.

Post-game content extends your playtime significantly if you engage with it. Most players beat the Champion and consider themselves done, but there’s 20-30+ additional hours of content if you pursue Pokédex completion, Legendary Pokémon, and competitive team optimization.

Conclusion

Pokémon Ash Gray stands out because it respects both the source material and the player’s intelligence. It’s not a story-light walkthrough, it’s a challenging, structurally sound Pokémon game that demands preparation and team-building competence.

The core takeaways: Type coverage beats type weakness. Grinding isn’t optional. Movesets matter more than raw stats. Gary Oak is a credible rival because his team reflects what a solid team looks like. The Elite Four punish negligence and reward strategy.

If you’re stuck, remember that Pokémon is fundamentally a game about matchups. Build a team with diverse type coverage, keep your levels competitive with the trainers you face, and think before you switch. You don’t need the “best” Pokémon, you need the right Pokémon for the job.

For players seeking something more hardcore, ROM hacks like A Comprehensive Guide to Pokemon Ash Grey – Bytesize Games or similar titles provide deeper challenges and mechanical innovations. But if you’re looking for a faithful, difficulty-balanced recreation of Ash’s journey? Pokémon Ash Gray delivers.

Now get out there, catch ’em all, and beat that Champion.
